The problem with the quick food poisonings is that it comes on very fast and once you expel it, you are fine. There is no time to take anything. At least that has been my experience with food poisoning. That is how you know that is not some "bug" and is actual food poisoning. I have a pretty fast metabolism, so maybe my experiences have been different. But the whole thing lasts no more then a half an hour for me. It is a miserable half an hour, but at least I know that once it all comes out, I feel better.
